Best Cob Led Grow Lights 2019 : Reviews and Buying Guide

If you are seriously thinking of growing weed, then one of the major equipments needed for your hydroponic garden system is the grow light. COB or the “chip on board” is the latest technology used for LED packaging wherein multiple LED chips are put together to form a single simulated light source or a single module that occupies minimum space and enhances the intensity of light . The COB LED grow lights pose to be a great alternative to the conventional HID, SMD or other modern LED grow lights not only because they produce more intense light and have a larger optimum coverage area  but also because they consume less electricity and have a higher life span and are more durable.  They also emit minimum heat and there is almost no risk of your cannabis plants getting damaged due to the heat from the grow lights. But these highly efficient grow lights have their share of disadvantages as well. One of the major dis-advantages of the COB LED grow lights is the lack of the color changing feature of the grow light. So you cannot adjust the color of the grow light in accordance with the stage of growth but you will have a full spectrum light that is capable of supporting all the growing phases all the time.

 If you do not choose your COB LED lights wisely you may also end up buying a poorly packaged light that may have too many diodes crammed into a single substrate which may lead to overheating and ultimately damaging the light, hence reducing its lifespan or lowering its efficiency to a great extent. These issues may be non-existent if the light is well packaged. Thus to guide you through the process of choosing the best COB LED grow light for your hydroponic garden set up, we will be providing you with a buying guide followed by the reviews of some of the best COB LED grow lights available in the market, so that you do not have any hassle and can end up making an intelligent decision.

Best Cob LED Grow Light Reviews

 Now that we have already provided you with the factors that largely influence the choice, let us have a look at some of the best COB LED grow lights.

#1. King X6 Led Grow Light

King Company is one of the leading manufacturers of LED Grow lights since 2012. A part of the X series of LED grow lights, which uses COB LEDs, the King X6 LED grow light is a 1800W dimmable grow light that has 6COB LEDs in the panel. Each COB LED has an intensity of 300W and has a full spectrum light that is designed for greenhouse and indoor plants and supports through all the growing stages. The third generation Sunlight spectrum COB LEDs provide a well balanced spectrum in the range of 380nm to 800nm with a decent share of UV and IR rays. The Epistar LEDs simulate sunshine and influence the optimum growth of plants. The King X6 has a high PAR value and a large coverage area (5’x5.5′ at 100%). From a height of 6” the PAR value of King X6 grow light is 1768, while when hung at 18” it is 779 and at 36” it is 268.The lightweight and compact grow light can be fit in almost any growing space, owing to its overall dimensions (15.8″x8.35″x2.44″) and weight (3kgs). The unit comes with a grow light hanger for a hassle free installation of the unit and a power cord to connect it to a power outlet.

It is extremely durable and has a lifespan over 50000hours and comes with a three years manufacturing warranty. But this highly recommended COB LED grow light lacks the daisy chaining option and is not waterproof, hence should be kept away from dripping water.

PROS:

  • 1800W COB LED Grow Light
  • Full Spectrum Light in the range of 380nm to 800nm
  • High PAR value with high coverage area
  • Dimmable with 0-100% intensity control

Best Cob Led Grow Light 2019 : Buying Guide

As mentioned earlier, there are certain factors that have to be kept in mind while buying a COB LED grow light. These are as follows:

  • Light Intensity and Coverage area:

This is one of the most important factors and the first one that should be considered while buying a COB LED grow light. The intensity and the coverage area of the light should be chosen in accordance with the size of your grow tent and the number of plants that are being considered. Once you have decided on the light intensity that would best suffice your needs, look for the actual intensity of the grow light and not the value that is equivalent to HPS grow light systems.

  • Light Spectrum:

You should carefully choose a full spectrum light that has a sufficient share of light rays in the UV as well as IR range. These rays in a controlled intensity favor plant growth. While UV light not only favours germination of seeds and activates the plants natural defense mechanism thereby protecting it from various diseases, the Infrared rays plays a part in the blooming phase and also increases the length of the stem.

  • Heat Output:

Though COB LED grow lights are known to generate less heat, a good heat dissipating mechanism is always essential and does not allow the damage of the grow light as well as the plants due to overheating. So you need to consider a COB LED grow light system that has a good heat dissipating mechanism. Cooling fans, vents or aluminum heat sinks are what we are looking for.

  • Lifespan:

Most COB LED grow lights have a great lifespan. Consider one that lasts for more hours so that you do not have to invest on them regularly.

  • Budget:

Budget is definitely a matter of concern when you are buying a COB LED grow light because these lights are not very cheap, but going for a cheaper version just to decrease the initial investment cost is not recommended. Consider buying a light that suffices your needs and has a well all rounded performance as well as a good lifespan and a well backed warranty so that your investment is worth the performance.

CONCLUSION:

So we have provided you with a list of some of the best COB LED grow lights in the market. The list has models with different outputs and features for you to choose from. Alternatively there is a buying guide that will also help you choose the COB LED grow light which will suffice your needs. A COB LED grow light that delivers a well balanced full spectrum light that mimics sunlight and has a high PAR value and an effective heat dissipation system along with a low running cost and a high life span is all that you need.
